Three laps into Sunday's race, the 24-year-old lost control of his McLaren and hit the barrier at Turn 12 before sliding off the circuit and out of the race.
Norris initially appeared to be struggling at the force of the impact on the rear of his car, taking a moment to confirm his condition over team radio while breathing heavily.
F1 officials took the Brit to the track's medical centre for initial checks before he was transferred to University Medical Center hospital for "further precautionary investigations".

Shortly after the finish of the grand prix, which Max Verstappen won ahead of Charles Leclerc, it was confirmed that Norris had been discharged.
He was soon pictured back at the circuit for the post-race debriefs.
“An unfortunate end to our Las Vegas GP weekend," he told the team website. "I just bottomed out on the restart, lost the rear and hit the wall.
"Not the way we wanted the weekend to end, especially considering the pace looked promising on Oscar [Piastri]’s side. Big thanks go to the medical staff for checking me over, and to the team for the work they’ll now put in on the car. One week to reset and go again for the season finale in Abu Dhabi.”
It capped a bad weekend for McLaren in Las Vegas, as both Norris and Piastri fell out of qualifying at the first hurdle and started near the back of the grid.
However, Piastri was able to finish tenth in the race as well as claiming the extra fastest lap point.
